EMPOWERING PERFORMANCE AND SAFETY

The new QX80 offers drivers greater levels of confidence at the wheel, with a suite of drive assist technologies that empower the driver. Despite the car’s size, the QX80 is easy to drive with full confidence.

New proactive drive assist technologies engender confidence at the wheel

The new QX80 offers a range of drive assist technologies – proactive safety innovations that support the driver in identifying and responding to other vehicles and potential hazards. Drawing on inputs from five cameras and three radars to read the road ahead and monitor the vehicle’s surroundings, the system allows the car to react accordingly.

The QX80 is newly-available with a range of technologies to inform the driver of their surroundings, help them avoid potential hazards and ease the monotony of driving in certain conditions. These technologies include: Lane Departure Warning and Prevention, Intelligent Cruise Control, Distance Control Assist, Predictive Forward Collision Warning, Forward Emergency Braking, Blind Spot Warning and Intervention and Backup Collision Intervention.

The drive assist technologies can operate between 20 and 90 mph (32 to 145 kph; certain right-hand drive markets operate up to 180 kph), while Intelligent Cruise Control can operate down to just 1 mph.

INFINITI has long been a pioneer in changing public perception of active and protective safety technologies. The brand led the way with a range of world-first application of proactive safety innovations, including Backup Collision Intervention, Lane Departure Warning and Prevention, and Predictive Forward Collision Warning.

Owners of the new QX80 are further assisted by the car’s new Smart Rear View Mirror. The new ‘digital’ mirror allows the driver to use the rear-view mirror as a standard mirror, or turn it into a monitor at the touch of a button. In the latter mode, it displays video from a camera mounted in the upper rear windshield. This enables drivers to see behind the car even when the rear window is blocked by fog, ice, passengers, or cargo. Furthermore, it improves visibility at night and in low-light conditions, with a High Definition Resolution (HDR) display combining two images into one, like a smartphone camera, at 60 frames-per-second. In icy conditions, owners need only scrape ice off the camera lens, instead of the entire rear window. As a safety measure, it also enables a clearer view behind the car in all conditions, with a wide-angle lens providing full visibility to the rear. Compared to a conventional rear-view mirror, with a 19 to 20° viewing angle through the car and out of the rear glass, the QX80’s new Smart Rear View Mirror offers up to a 48.1° view.

Comfort-focused suspension for a calm, relaxed drive

The new QX80 offers a taut yet comfort-oriented ride, the suspension engineered to filter out poor road conditions and keep occupants comfortable. Whether at a cruise, on busy urban roads, or on a winding highway, the QX80 remains composed and controlled at all times.

The QX80 assures a calm, refined ride for all occupants and is focused, first and foremost, on comfort. Despite the comfort-biased brief for the fully-independent double-wishbone suspension, the QX80’s unique Hydraulic Body Motion Control (HBMC) technology limits excess body-roll under more severe cornering.

HBMC monitors body lean and roll as the QX80 turns into a corner, and adjusts the suspension to create a smooth, flat ride. Hydraulic cylinders are connected to the shock absorbers, and linked to one another with high-pressure hydraulic channels. Two accumulators monitor body roll and adjust suspension stiffness on each side of the car by transferring oil between the hydraulic cylinders.

As the car corners and the body starts to lean, HBMC firms up the suspension on one side of the car to counter this effect. With HBMC equipped as standard, the QX80’s lean angle is around 35% flatter than that of the segment best-seller, without sacrificing the cruising comfort expected of a luxury SUV.

For the new model, the suspension’s damping force also has been reduced by 30% at every corner, isolating the cabin further by absorbing higher-frequency vibrations. This has been achieved by retuning the characteristics of the QX80’s shock absorber pistons.

Rear Auto-Leveling Suspension automatically adjusts suspension pressure to maintain the optimum ride height with cargo in the trunk or a trailer on tow. This allows the QX80 to tow up to 8,500 lbs (3,855 kg), and carry up to 2,694 liters (95.1 cu ft) of interior cargo volume with third- and second-row seats folded. By keeping the vehicle at its optimal height, the QX80 remains stable and continues to offer responsible handling and braking, improving driver confidence when towing or carrying heavier loads.

Gathering feedback from existing QX80 customers, INFINITI has also changed the vertical angle of the radial steel belt in the tire walls. This reduces vertical deflection by 5% over the outgoing QX80, enabling the car to better absorb small vibrations and road impacts when driving over rough or broken surfaces.

Finally, the design changes to the car are accompanied by optimized aerodynamic properties. With a drag co-efficient of 0.36 Cd – competitive with the most aerodynamic designs in the segment – the new QX80 features a range of modifications to better direct air over, around and under the vehicle. INFINITI has applied its ‘zero lift’ approach, maximizing stability at higher speeds. Revisions to the car include a new under-body cover, reshaped to improve air flow and reduce air pressure beneath the body and better direct air away from the rear tires to reduce drag.

The redesigned body also enhances air flow, particularly off the rear, to minimize drag-inducing turbulence. These changes reduce the effects of wind turbulence at higher speeds, leaving the driver feeling more in-control and connected with the road.

The QX80 is available with rear-wheel drive or four-wheel drive, the latter enabling all-wheel traction when conditions require it, and off-road capability when the driver demands it

Effortless performance and controlled application of power in all conditions

In partnership with the advanced suspension, the QX80’s powertrain ensures effortless and refined progress. With a powerful 5.6-liter V8 engine driving the rear or both axles, the new QX80 remains the consummate performer in even the worst driving conditions.

The QX80 is available with rear-wheel drive or four-wheel drive, the latter enabling all-wheel traction when conditions require it, and off-road capability when the driver demands it. With optimal all-season power delivery, the rear-biased drivetrain defaults to rear-wheel drive, continually adjusting power distribution between front and rear axles.

Drivers can customize the all-wheel drive system via a dial in the center console. The system sits in ‘auto’ mode by default, using a computer-controlled transfer case to instantly redistribute engine torque to the wheels with the most traction. Permanent high- and low-range all-wheel drive settings are also available. The high-range setting is designed to take on moderate off-road driving and snow; the low-range function empowers drivers to tackle more demanding off-road conditions, with steeper inclines and declines, when more traction is needed.

The all-wheel drive system is backed up by the QX80’s four-wheel Active Brake Limited Slip (ABLS) system, which responds to wheel-spin by automatically applying brakes to each spinning wheel, and redistributing torque to other wheels to maximize traction and control.

Both rear- and all-wheel drivetrains are paired with an advanced 5.6-liter DOHC V8 engine, delivering ample on-road performance. Combining the combustion efficiency of Direct Injection Gasoline (DIG), and the responsive acceleration of VVEL (Variable Valve Event and Lift) technology, the V8 engine produces 400 hp (298 kW) and 413 lb ft of torque. The smooth-shifting seven-speed automatic transmission, fitted as standard to every model, allows the driver to access the engine’s power and torque reserves at any time. The automatic transmission features Adaptive Shift Control (ASC), and manual shift mode with Downshift Rev Matching.
